It's hard to be a mysophobe – a person who fears germs. The everyday world can pose a major hazard to you, especially when the subjects of these germaphobe photos start popping up in your own life. Photos that trigger your germaphobia stoke a primal fear, making you hyper-aware of the bacteria lying in wait on every doorknob or subway seat. Animals in drinking fountains and grubby baby hands are all pictures germaphobes understand completely.

On a day-to-day basis, millions come in contact with the world's dirtiest objects without ever considering how gross they might be. The inevitability of poor hygiene makes these germaphobia pictures all the more triggering – documented evidence of a world civilized in name only.
